HENRY M. MCOAFFERTY, OF MONTROSE, COLORADO.

COMBINATION-PLOW.

SPECIFICATION forming part of Letters Patent No. 478,884, dated July 12,1892.

Application filed October 13, 1891. Serial No. 408,557. (No model.)

To all whom it may concern:

Be it known that I, HENRY M. M OCAFFERTY, of Montrose, in the county ofMontrose and State of Colorado, have invented anew and ImprovedOombination-Plow, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in agricultural implements; and itsobject is to produce a combination sulky-plow and roller which willthoroughly plow the soil, which will roll it nicely at the same time,and in which the roller forms one of the main wheels of the machine. Themachine is especially advantageous from the fact that the soil rollsbetter while it is somewhat moist and mellow, as the clods will breakeasier; and, moreover, when the ground is rolled at'the same time it isplowed the moisture is retained for a long time. The soil being moreplastic at this time also fills all crevices and completely covers allweeds and vegetable matter, so that they will rot quickly and leave theground in good condition for the drill or planter, as the case may be,thus saving the usual amount of harrowing and rolling.

' plan showing the manner in which the front end of the frame is coupledto the plow-beam and to the mechanism for moving the frame and plow.Fig. 5 is a broken detail cross-section on the line 5 5 in Fig. 4. Fig.6 is a broken detail rear elevation of the lever mechanism for movingthe rear end of the plow, and Fig. 7 is a broken side elevation of thesame, showing a portion of the frame in section.

The main frame 10 is of an essentially triangular shape, as best shownin Fig. 1, and is formed of the side pieces 11 and 12 and the rearcross-piece 13, the pieces being suitably united at their adjacent ends.At one end of the cross-piece 13 is a bearing-axle 13, which enters thehub of the wheel 14 in the usual manner, and on the opposite side of theframe the parts 11 and 13 where they meet are bent rearward, as shown at15, and the part 13 terminates in a suitable knuckle 16, adapted toreceive the couplingpin 17, by means of which the yoke 18 of the roller19 is hinged to the main frame. The lower end of the pin'17 extendsthrough a collar 17 as best shown in Fig. 3, and this collar connects bymeans of a brace with a clevis 17' on the part of the frame, the aboveconnection serving to prevent the frame and yoke from sagging. Theroller 19 is of common construction, being made up of a series offlat-faced wheels, and the yoke 18 embraces one-half the roller andcarries the axle of the same. The front end of theframe 10, where thetwo side pieces 11 and 12 are united, is elongated, as shown at 20 inFig. 1, and this front end of the frame is vertically adjustable and ismounted on the rod 21 in the manner described below. This rod 21 is heldin a nearly vertical position, as best shown in Figs. 2 and 3, isdoubled in the middle, as shown at 22, which doubled portion forms thetop of the rod, and the ends of the red are secured to an axle 23, whichcarries a wheel 24, adapted to run in the furrow, and the outer end ofthe axle is connected by a brace 25 with the tongue 26, which tongue isconnected with the upper portion of the rod 21 by means of clevises 27,which clamp the members of the rod to the angle-piece 28, which issecured to the tongue and supports the clevises.

On the inner member of the rod 21 are sliding collars 29, which supporta rectangular frame 30, and this frame embraces. the elongated end 20 ofthe main frame and is secured thereto by a bolt 31, which bolt alsoforms a support for the plow-beam, as described below.

To the extreme front end of the frame 10 are pivoted links 32, which areadapted to support the clevisby which the machine is drawn, and a stayrod or bar 33 extends forward from the bolt 31 and parallel with thelinks 32, and the clevis-pin 34 is carried in the free ends of thestay-bar and links and supports the clevis 35. A pin 36 extends throughthe links 32 and also through one of a series of holes in a strap 37,which strap is pivoted at its upper end to the short end of a lever 38,and the lever is pivoted to a drum 39, which turns on one member of therod 21, and is held in place by collars 40. The lever 33 extendsrearward to a point where it may be easily reached from the seat ll ofthe machine, and the seat is supported on the usual spring-bar 42, andis also provided with a foot-rest 43. A segmental rack ll is alsosupported on the drum 39, so that it will always hear the same relationto the lever 38, and this rack is arranged adjacent to the lever and isadapted to engage a sliding bolt 45 on the lever, the bolt connecting bya rod 46 with a spring-pressed handle 47, which is pivoted on the lever38 near its free end, and by means of which the bolt 4-5 may be releasedfrom the rack.

The rack mechanism for holding the lever is of common construction, andby its use the lever may be held in a desired position and the frame andplow held at the requisite height. By adjusting the strap 37 in relationto the frame 10 the plow may be adapted for shallow or deep plowing. Theplow 4:8 is of the usual kind, and is arranged centrally beneath themain frame. The plow is provided with the usual plow-beam 49, whichextends forward, and the front end of which is held between wear-plates50 in the elongated portion 20 of the main frame, the plow-beam, plates,the main frame, and the rectangular frame 30 all being clamped togetherby the bolt 31, as best shown in Fig. 5.

The plow-beam has attached to it by means of a clevis 51 a eolter-bar52,havinga curved arm 53 at its lower end, and this arm carries at itsfree end a rolling eolter 54:, which is arranged adjacent to theplow-point in the usual manner. The rear portion of the plow isconnected by a brace 55 with the lower crank end of the lever 56, whichlever is pivoted on a suitable support attached to the cross-piece 13 ofthe main frame and extends upward to a point within easy reach of thedriver. The plow also connects by means of straps 57 with a crank 58 ofthe shaft 59, which shaft is mounted in a suitable support 60 on themain frame and is connected with the lever 56, and by moving the leverthe plow may be raised or lowered, as desired.

The usual form of segmental rack 61 is arranged adjacent to the lever,and the lever is provided with a catch mechanism to engage the rack likethat provided for the lever 38 and already described.

The operation of the machine is as follows: The plow is let into theground by means of the lever 56 and is adjusted by the lever 38 in themanner already described, so as to plow the requisite depth, and as thefurrow is turned it will be thrown into the path of the roller 19,whichwill roll the soil smoothly and thoroughly.

I have shown the machine provided with a single plow and roller; but itwill be understood that any desired number of plows may be used-that is,a gang of plows-and the roller may be made wide enough to cover all thefurrows, or a series of separate rollers may be used.

In the drawings I have shown the various parts of the frame connected byclevises; but, if desired, bolts may be substituted.

llaving thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with the plow and itsframe, of a wheel supporting the frame at the landside and a land-rollerhinged centrally between its ends at its forward side to the 0ppositeside of the frame to support it and adapted to have a free lateralswinging movement, substantially as set forth.
